MDF Type

[the_g_ster]

Currently planning some pretty serious jobs in the house (2 built in wardrobes and kitchen) and have a query on MDF.

I got some 18mm Moisture resist stuff, but it appears to be a sandwich of some green core (about 8mm) and then faced with normal mdf. Am I going to have trouble finishing this type? I expected it to be all green as per the stuff I have seen some of you guys on here.

Cheers, G

PS, Will be posting some pics of my attempts at all this soon.

Hi g
the moisture resistant mdf is just stained green in the centre so it can be distinguished between that and normal. there is no difference in quality, in fact a little better if your moulding into it. The sheets that are totally green are standard MDF that has been coloured.

Hi G

In the trade this type of MR MDF goes by the name of liquorice allsorts. It’s OK but not as good as 100% green. I have used some MR MDF on the outside of my house for the past fifteen years and it is as good now as when I first put up and that was 100% green but some allsorts MDF as been very disappointing only lasted one winter.
So when a suppler sends me the allsorts grade it gets left on the van and sent back.

I only use MR MDF it machines a lot better than the standard stuff and paints and seals a lot better.

Thanks Alan, I will try and find some 100% stuff for the sprayed fronts as that's what's going to be the real challenge.

Wickes sell the all green type

The MR MDF I have used is 100% Green no sandwich...

Does anybody know if Wickes cut down for you?

I don't fancy the handsaw in the carpark trying to wedge it in the car.

Mine doesn't...

B&Q ? - battery powered saw? Or how about that new technology hand operated panel saw, only I have been told it very cheap to run and very portable.

Yeh, then you can take it home on ya hoss. :lol:

Grin, yep, Festool don't do one of those......

Still, it's 0 Volt, easy to store, do get some chip out, and run time is for as long a the user can put up with it.

As far as I'm aware, its a brand related difference. The brown with green interior is Medite MRMDF on thicknesses over 15mm. I agree its not as dense as all green (caberwood?) but its still definitely moisture resistant and still much more dense than standard MDF

Like most others, I only ever use MR MDF, and my supplier normally sends me the 'all green' variety.

Occasionally though, I have been sent the 'sandwich' type, which seems to be from an alternative manufacturer, as Tim says.

I've never discerned any difference in performance with regards to machining or finishing.

I'm visiting my supplier in the morning to pick out some nice veneered boards for doors so I'll ask him what he knows.

My local yard (Nixon Knowles) had a display up a while back, showing a new product which was MR but normal sand colour. "It's not green but it's still MR" said the poster. I'm afraid I don't recall the brand.

As Tim says Caber is green all the way through and thats what I tend to use, Medite tends to just be green in the center. It will loose its green tinge on the surface if left exposed to light for any length of time as its just a dye to melp you tell what it is. They also dye Fire resistant MDF red and exterior Grey.

MDF may go the same way as chipboard

Spoke with my board supplier and it turns out that the 'sandwich' stuff is made by Medite and he only gets it in when he runs out of the all green stock which in his case is from Finsa in Spain.

He tells me that a lot of his customers think that the Medite boards are not as good.

Thanks Dan, I am going to get some all green for the face fronts that will be sprayed to make sure I hopefully have the best chance of obtaining a good finish.
